“…Changes in the structural and magnetic characteristics correlate with changes in the electronic structure with increasing substitution concentration. A similar correlation of changes in the electronic and crystalline structures was observed in bismuth pyrovskites [20,21]. The electrical resistivity was measured by the standard four-probe direct current method in the temperature range 77-300 K in a magnetic field of up to 12 kOe and indicates the semiconductor type of conductivity of the synthesized compounds of the MnSe1-ХTeХ system.…”

The effect of anionic substitution on the structural, magnetic, and kinetic properties of chalcogenides of the MnSe1-XTeX system in the temperature range of 77-400K in magnetic fields up to 12 kOe was studied. With an increase in the substitution concentration, changes in the structural and magnetic characteristics, which correlate with changes in the electronic structure, were found. The type and mobility of the main current carriers were determined from the Hall effect measurements.

To establish the existence of dipole glass in the chromium-substituted bismuth pyrostannate solid solutions, the frequency and temperature dependences of the permittivity have been measured in the temperature range of 300-750 K. The field and dynamic dependences of polarization in the temperature range of 80-550 K have been determined. Using the Raman scattering spectra, the absence of inversion center has been established. The maximum of electrical resistance has been found in the vicinity of the dipole moment freezing point. The carrier type has been determined from the thermopower data. The polarization relaxation is shown to be nonexponential. The experimental data are explained within the model of dipole glass in the αphase and the model of charged crystalline domain walls with the electronpolarization relaxation mechanism above the α-β structural transition.

“…In the vicinity of phase transitions, the system reveals large fluctuations of the order parameter. Phase transitions are realized in magnetic [1][2][3], crystalline [4][5][6] and dielectric [7][8][9] systems. In this temperature range, the system becomes unstable and nonequilibrium effects appear.…”
